Or in the fishes! Sharks to be exact!! Sleeping with the fishes would be more of a Troy McClure/Kanye West type of thing.
Patched Together has a "Chum Buddy" sleeping bag that is 7 feet long, hand sewn and about 30 lbs (poly-fill.) It's a whopping $200 (free shipping to continental US) which is pricey, but of course you've got to pay the big bucks for something this cool! You can bet, as soon as they're available, I am getting one of these!
And what gift goes with this ultra cool sleeping bag? Shark slippers!! Cuddly, fuzzy and only $13! Get them here
